1.Obunene bw'okukozesa .

   (1). Esiigiddwa ku kapiira akatali kajjudde: nga NR, BR, NBR, IR, SBR, n’ebirala.

   (2). Siiga ku kapiira akajjudde: nga EPM esobola okufuulibwa vulcanized ne peroxide yokka, EPDM esobola okufuulibwa vulcanized ne peroxide ne sulfur.

   (3). Esiigiddwa ku kapiira k’enjegere ak’enjawulo: gamba nga q vulcanization.

2. Ebifaananyi by’enkola ya peroxide vulcanization .

(1). Ensengekera y’omukutu gwa kapiira akayitibwa vulcanized cc bond, n’amaanyi g’enkolagana amangi, okutebenkera kw’eddagala eringi, n’okuziyiza okulungi ennyo eri okukaddiwa kw’ebbugumu ne okisigyeni.

(2). Vulcanized rubber erina deformation entono ey’olubeerera, elasticity ennungi ate nga ekola bulungi dynamic performance.

(3). Obukuumi obubi obw’okulongoosa n’obungi bwa peroxide obw’ebbeeyi.

(4). Mu kusiba static oba ebbugumu eringi static sealing products zirina enkola ez’enjawulo.

3-ekyatera okukozesebwa peroxides .

Ebirungo ebikola perokisayidi ebitera okukozesebwa ye alkyl peroxides, diacyl peroxides (dibenzoyl peroxide (BPO)) ne peroxy esters. Mu byo, dialkyl peroxides zikozesebwa nnyo. nga: diisopropyl peroxide (DCP): mu kiseera kino kye kisinga okukozesebwa ekirungo ekikola enseenene.

2,5-dimethyl-2,5-(di-tert-butylperoxy) hexane: era emanyiddwa nga bis-dipecentyl .

4. Enkola ya Peroxide Vulcanization .

Ekibinja kya perokisayidi ekya peroxide kyangu okuvunda olw’ebbugumu okukola ebirungo ebiyitibwa free radicals, ebivaako ensengekera y’ekika kya free radicals cross-linking reaction y’olujegere lwa molekyu ya kapiira.

5. Ensonga enkulu eza peroxide vulcanization:

(1). Dosage: ekyukakyuka n’ebika bya kapiira eby’enjawulo .

Obulung’amu bw’okusalasala kwa perokisayidi: Molekyulu ya 1g eya perokisayidi esobola okukola grams mmeka eza molekyu za kapiira zikola okusalasala kwa kemiko.Singa molekyu 1 eya perokisayidi esobola okufuula molekyu za 1G eza kapiira ezikwatagana, obulungi bw’okuyunga (cross-linking efficiency) buba 1.

Okugeza: obulungi bw’okuyunga (cross-linking efficiency) bwa SBR buba 12.5; Obulung’amu bw’okusalako (cross-linking efficiency) bwa BR buli 10.5; Obulung’amu bw’okusalasala kwa EPDM, NBR, NR buba 1; Obulung’amu bw’okusalako (cross-linking efficiency) bwa IIR buba 0.

(2). Okukozesa Active Agent ne Co-sulfurizing Agent okulongoosa enkola y’okusalasala .

Omulimu gwa ZnO kwe kulongoosa obuziyiza ebbugumu bw’ekizigo, so si activator. Omulimu gwa stearic acid kwe kulongoosa okusaanuuka n’okusaasaana kwa ZnO mu kapiira. HVA-2 (N,N’-phthalimido-dimaleimide) nayo ekola bulungi mu peroxide.

Okwongerako ekirungo ekiyambako eky’okuwunyiriza: okusinga kimyufu kya kyenvu, n’ebintu ebirala ebiyamba okusalasala nga divinylbenzene, trialkyltriyate, carboxylates ezitajjudde, n’ebirala.

(3). Oteekamu ebirungo ebitono ebya alkaline, nga MGO, triethanolamine, n’ebirala, okulongoosa obulungi bw’okusalasala, weewale okukozesa slot carbon black ne silica n’ebirala ebijjuza asidi (asidi okukola free radicals passivation); Antioxidants okutwalira awamu zibeera amine ne phenolic antioxidants, era nga nnyangu okukola free radicals passivation, ekikendeeza ku bulungibwansi bwa cross-linking, zirina okukozesebwa kitono.

(4). Ebbugumu ly’okufuuka vulcanization: lirina okuba waggulu okusinga ebbugumu ly’okuvunda erya peroxide .

(5). Vulcanization Time: Okutwalira awamu emirundi 6~10 egy’ekitundu ky’obulamu bwa peroxide.

   Ekitundu ky’obulamu bwa perokisayidi: Ku bbugumu erimu, okuvunda kwa perokisayidi okutuuka ku kitundu ky’obungi obw’olubereberye obw’ekiseera ekyetaagisa, nga bulagibwa mu T1/2.

   Singa ekitundu ky'obulamu bwa DCP ku 170°C kiba 1min, olwo obudde bwakyo obw'ekiwujjo obulungi bulina okuba 6~10min.
